For additional reference information refer to:

• National Fire Protection Association (USA): www.nfpa.org

• Fire Industry Association (UK): www.fia.uk.com

The design concentration for Class A and C fires applies to systems designed to meet and comply with

FM5600, and NFPA 2001, Edition 2015 requirements. As such, our customers are reminded and advised:

• In accordance with 4.3.1.2 and 4.3.1.3 of NFPA 2001, Edition 2015, automatic detection and

automatic actuation shall be used. Manual actuation is permitted only if acceptable by the authority

having jurisdiction.

• Designers should also take note of 4.3.5.6 in NFPA 2001, Edition 2015 with regard to discharge

delays.

• The designer should also review A.5.4.2.4 in NFPA 2001, Edition 2015 and confirm that a protected

Class A hazard does not include any Class B materials (flammable or combustible liquids or gases)

which would classify the protected space as a Class B hazard.

• In addition, the designer should refer to section A.5.6 in NFPA 2001, Edition 2015 and confirm that

the protected space does not include electrical equipment that will not be de-energized prior to or at

the time of Agent discharge. Such energized electrical equipment has the potential to act as a

persistent re-ignition source. If electrical equipment cannot be de-energized, the design Agent

concentration shall be at least that required by 5.4.2.5 in NFPA 2001, Edition 2015. In some cases

consideration should be given to the use of extended Agent discharge or higher design Agent

concentration. When exploring these options, keep in mind the possibility of the formation of

combustion and decomposition products. Please contact applications engineering for design guidance

in such instances.

SAFE CYLINDER HANDLING PROCEDURES

Before handling Kidde IGS products, all personnel must be trained in the safe handling of the containers

as well as in the proper procedures for installation, removal, filling, and connection of other critical devices,

such as flex hoses; actuation devices; pressure monitoring devices; transportation safety caps, guards, or

shrouds; and anti-recoil devices.

READ, UNDERSTAND and ALWAYS FOLLOW the design, installation, operation and maintenance manuals,

owners manuals, service manuals, etc., that are provided with the individual systems.

The following safety procedures must be observed at all times:

TRANSPORTING CONTAINER

Containers must be shipped securely either upright in steel stillages or horizontally on pallets using a

minimum of 3 bands to secure the container/s to the pallet.

On site, containers must not be rolled, dragged, or slid, nor allowed to be slid from tailgates of vehicles. A

suitable hand truck, fork truck, single cylinder trolley, roll platform, or similar device must be used.

ROUGH HANDLING

Containers must not be dropped or permitted to strike violently against each other or other surfaces.

STORAGE

Containers must be stored standing upright where they are not likely to be knocked over and the containers

must be secured.

For additional information on safe handling of compressed gas cylinders, see CGA Pamphlet PI titled

“Standard for Safe Handling of Compressed Gases in Containers”. CGA pamphlets may be purchased from

The Compressed Gas Association: http://www.cganet.com

ANTI-RECOIL SAFETY CAP

• Each Agent cylinder is factory equipped with an anti-recoil safety cap installed on the valve discharge

outlet, and securely fixed to the valve via a stainless steel, PVC coated cable to prevent loss. This

device is a safety feature, and will prevent discharge when installed if the cylinder is actuated

accidentally.

• The anti-recoil safety cap must be installed on the valve outlet AT ALL TIMES except when the

cylinders are connected into the system piping.

WARNING

Any area in which inert gas agent is used or stored must be properly ventilated.

A person working in an area where air has become enriched with agent can

become unconscious without sensing the lack of oxygen. Remove the victim to

fresh air. Administer artificial respiration if necessary and summon a physician.

Never dispose of liquefied agent in an indoor work or storage area.

WARNING

Pressurized (charged) cylinders are capable of violent discharge and, as such, are

extremely hazardous. Pressurized cylinders must be handled safely to avoid accidents

that could cause bodily injury, death, or property damage.

WARNING

The instructions contained in this foreword and throughout the manual must be

followed in the exact sequence as written to prevent serious injury, death, or

property damage.

April 2020 iv 06-237619-001

SAFETY TRANSPORTATION CAP, GUARD, OR SHROUD

The Safety Transportation cap, guard, or shroud is factory installed on the cylinder. The safety

transportation cap, guard, or shroud covers the cylinder valve to protect it during transportation and

handling. No attachments (release unit or slave gauge assemblies) are to be connected to the cylinder

valve during shipment, storage, or handling.

INSTALLATION

THIS SEQUENCE FOR CYLINDER INSTALLATION MUST BE FOLLOWED AT ALL TIMES:

1. Install cylinder into bracketing.

2. Remove the Transport cap.

3. Remove the anti-recoil safety cap and connect all cylinder valves into system piping using

appropriately sized discharge hose.

4. Install all pilot hoses, Pilot Line Bleed Valves etc. leaving the release unit available for installation by

the commissioning engineer only.

REMOVAL FROM SERVICE

THIS SEQUENCE FOR CYLINDER REMOVAL MUST BE FOLLOWED AT ALL TIMES:

1. Remove all release units, slave cylinder pressure gauge units, and pilot lines from cylinder valve.

2. Disconnect discharge hose at the valve outlet.

3. Immediately install anti-recoil safety cap on valve outlet.

4. Attach the transport cap to the cylinder/valve assembly.

5. Remove cylinder from bracketing.

WARNING

In order to prevent injury in the event of accidental cylinder discharge, the discharge

hose must be connected to the system piping before attaching to the cylinder valve

outlet.

WARNING

The safety pin for the manual release must be fully inserted and secured using anti-

tamper seal before attempting to fit the release unit to the valve actuation port

WARNING

The cylinder valve anti-recoil safety cap must be immediately available for installation

on the cylinder valve outlet before disconnecting the cylinder discharge hose from

system piping. If the safety cap is missing obtain a new safety cap from Kidde Fire

Systems.

WARNING

Failure to follow all instructions in this manual on the use and handling of system

components could result in serious bodily injury, death, and property damage in the

event of inadvertent and unexpected cylinder discharge.
